Abstrak/Abstract Plant Growth Promoting Rhizobacteria has been known for its ability to induce plant resistance on shallot against twisted disease. Its ability as a bioprotectant agent is estimated to be comparable to the efficacy of Trichoderma which is currently widely used as a biological control agent. This study aimed to determine the content of jasmonic acid, salicylic acid, peroxidase, and disease suppression in shallot by application of Bacillus velezensis B27, Bacillus cereus RC76, and combination of both rhizobacteria. The application was carried out with tuber dipping for 30 minutes in each treatment with a bacterial density of 10^8 CFU/ml. Application usingTrichoderma was used as the comparison treatment, and the control plot was not given any treatment. Pathogeninoculation was carried out simultaneously during planting using Fusarium acutatum with a spore density of 10^6 CFU/ml. The jasmonic and salicylic acids content was measured using the High-Performance Liquid Chromatography method, and the peroxidase content was determined using the spectrophotometric method. Disease suppression was measured at 10-day intervals. The results showed that treatment with Bacillus cereus RC76 increased jasmonic and salicylic acid levels, while application with Bacillus velezensis B-27 showed the highest level of peroxidase. Treatments with Bacillus spp. were able to suppress twisted disease by 72.2% to 100%. This study demonstrated that application of Bacillus spp. suppressed twisted disease on shallot and quantitatively increased the content of jasmonic and salicylic acid as induced resistance mechanism against pathogens.
